Definitions

  • the present invention relates to a safety system for an autonomous ground vehicle. Specifically, the present invention deals with the need to provide a safety mechanism to avoid an autonomous ground vehicle operating at too high a speed in the proximity of human operators.
  • the present invention provides a method for avoiding collisions between a vehicle and personnel comprising the steps of: determining the locations of personnel within a predetermined range of said vehicle; determining the proximity to said vehicle of said personnel; applying a speed profile to said vehicle for reducing the speed of the vehicle or stopping the vehicle.
  • the present invention also provides a safety system for a vehicle comprising: a vehicle control system; and a safety system; wherein vehicle position data and personnel position data is provided to the safety system; and if the vehicle position data and personnel position data are determined by the safety system to indicate that said vehicle is in close proximity to personnel, the safety system applies a speed profile to the vehicle control system causing the vehicle to reduce speed or stop.
  • Figure 1 is a drawing showing an illustration of a safety system in an autonomous vehicle.
  • Figure 2 is a drawing showing the illustration of an example situation involving an autonomous vehicle and several personnel.
  • FIG. 1 there is shown the basic systems required to provide an embodiment of the present invention, including a vehicle autonomous mission system 20 which provides decision making outputs 40 to a vehicle control system 60.
  • the vehicle autonomous mission system 20 is fed with position data 10 for any personnel involved in a given mission.
  • the position data 10 is simultaneously fed to a safety system 30 which is separate to the autonomous mission system 20 and which can send a safety override signal 50 to the vehicle control system 60 if it determines that the position data 10 meets given safety criterion.
  • the position data is, in this embodiment, GPS position data for the vehicle 100 and also for any personnel 130 in the theatre of operation of the vehicle 100.
  • the position data is supplied by handheld units having GPS positioning devices and which can transmit data to the vehicle 100 that the personnel 130 carry on their person.
  • the vehicle is similarly equipped with a GPS positioning device.
  • the autonomous mission system 20 receives orders from a remote or local operator and translates these orders into commands to operate the vehicle to carry out said orders.
  • Vehicle control system 60 receives the commands from the autonomous mission system 20 and translates these commands into simpler commands for the components of the vehicle, for example co-ordinating the steering, throttle and gears to operate in conjunction to make the vehicle drive in a straight line.
  • the safety system 30 is employed to reduce the risk of a collision between vehicle and personnel where personnel stray into this hazard zone.
  • the safety system uses several criterion to determine the level of risk to personnel from the vehicle, including whether the vehicle is heading in the direction of personnel or whether the relevant personnel are located away from the direction of travel of the vehicle, even taking into account errors in location. If the safety system determines that there is risk to personnel potentially in the direction of travel of the vehicle then a safety override signal is sent to the vehicle control system to apply a speed profile or, ultimately, stop the vehicle.
  • the vehicle 100 is shown with two zones surrounding it, a GPS error zone 1 10 (dashed line) and the safety exclusion zone 120 (solid line). Surrounding the vehicle 100 are three personnel 130.
  • the autonomous mission system 20 when processing an order to, for example, follow one of the personnel 130, would plot a course to act accordingly, following at a safe distance from the person 130 it is meant to follow. If another of the personnel 130 is also moving, and happens to be moving closer to the vehicle 100 then the safety system 30 will trigger once a person 130 is within a outer perimeter distance from the vehicle 100.
  • the first stage of the safety system is to apply a lower speed profile to the vehicle 100 through the application of any or a combination of: shifting the gears down to a slower speed gear; applying the brakes to bring down the speed of the vehicle; and/or applying a speed limit to the vehicle that is more appropriate to a vehicle travelling in proximity to humans.
  • the safety system applies one or more further stages of lower speed profiles in iteration until the vehicle is deemed too close to a person 130 and the vehicle autonomous management system is overridden to order the vehicle control system to stop the vehicle.
  • the lowest speed profile can be re-applied to the vehicle control system and the vehicle autonomous management system can be handed back control of the vehicle from the safety system.
  • the speed profiles can be stepped through up to the maximum speed profile to allow orders to be executed by the vehicle autonomous management system at full speed.

Abstract

La présente invention concerne un système de sécurité destiné à un véhicule terrestre autonome. L'invention concerne précisément la nécessité de fournir un mécanisme de sécurité qui permette d'éviter à un véhicule terrestre autonome de fonctionner à trop grande vitesse à proximité d'opérateurs humains. En conséquence, l'invention concerne un procédé permettant d'éviter les collisions entre un véhicule et du personnel, qui comprend : la détermination des positions du personnel dans une plage prédéfinie dudit véhicule; la détermination de la proximité avec ledit véhicule du personnel; l'application d'un profil de vitesse au véhicule afin de réduire la vitesse du véhicule ou d'arrêter le véhicule. En conséquence, l'invention concerne également un système de sécurité destiné à un véhicule qui comprend : un système de commande de véhicule; et un système de sécurité; les données de position du personnel et les données de position du véhicule sont fournies au système de sécurité; et si le système de sécurité détermine que les données de position du véhicule et les données de position du personnel indiquent que le véhicule est à proximité du personnel, le système de sécurité applique un profil de vitesse au système de commande du véhicule, ce qui amène le véhicule à réduire sa vitesse ou à s'arrêter.
